NEW BRITAIN, connncrrcor, A. conronarron or conro'on-smrnnme HOLDER.-

Patented Dec. 10, 1912.

Application filed July 18.1912. Serial No. 710,140.

To all 'whom it may concern Be it known that I, Josnrn M. HANGE,

: a citizen of the United States, residing at New .Britain, Hartfordcounty, State of Connecticut, have invented certain new and usefulImprovements in Tool-Sharpening Holders, of which the following 1s afull, clear, and exact description.

The present invention relates. to holders for cutting tools andspecifically to one designed for use in connection with various forms ofsharpening surfaces and affording means for adjustment to suit varyingconditions as well as combining simplicity and strength of structurewith a wide range of use. These and other advantages will appear fromthe more detailed descriptionfollowing taken in connection with theaccompanying drawings forming part thereof and illustrating a preferableembodiment of the invention.

In these drawings, Figure 1 is a top plan view of the holder having aplane cutter mounted therein and in operatlve position on a flatsharpening surface. Fig. 2 is a side elevation, partly in section, ofthe parts shown in Fig. 1. vFig. 3 is an end elevation of the holder.supporting and guiding carriage. Fig. 4 is a transverse sectional viewtaken through the bracket carrying the tool planting screws.- Fig. 5 isa side elevation of the holder having a chisel mounted therein and inoperative sharpening position on a grind stone.

Referring to the drawings by numerals: the main body of the holder ispreferably formed as an integral structure, such as an iron casting, andembodies adownwardly inclined portion 1 of skeleton form serving as atool seat and having an upstanding bracket 2 extending transverselythereover and spannin the tool seat, this bracket being provide with aplurality of threaded bores 3 therein extending longitudinally of thebracket and adapted toreceive clamping screws 4 whose lower ends, whenscrewed down, will engage a cutting tool, such as the plane cutter 5,and clamp the same on its seat 1. In the drawings I have shown threespaced threaded bores so that wide as well as narrow cutting tools maybe clamped on the cutter seat of the holder. The spacing and number ofthese bores, however, may be varied within the practical accomplishmentof the object recited. From the upper and therefor.

rear end of the inclined seat portion 1, the main body portion extendssubstantially horlzontally in .the.form of an integral arm 6. At itsfarther or rear end, forming the mar end of the body portion, this armis formed with a I threaded bore 7.' The threaded standard 8 of asupporting carriage 9 engages with this bore and because of its threadedengagement therewith is enabled to rest'on a base and support the toolholder with the edge of the cutting tool car ried'thereby inclined atvarious angles relative to a sharpening surface with which it maycooperate. In order to securely lock the supporting carriage in itsadjusted position relative to the arm 6, I preferably form one or moregrooves'lO longitudinally of its threaded standard 8 :and provide thearm 6 at its farther end with a thumb screw 11 threaded into theextremity of the arm to extend transversely therethrough and into thebore 7 so that it may be moved to bring its inner end into engagementwith a groove 10 to lock the standard Sagainst adjustment-destroyingmovement. The carriage 9 carries at its base a suitable roller 12 whichforms an anti-friction bearing and support In Figs. 1 and 2 I have shownthis roller resting on a base and the tool frame and tool cooperatingwith a flat sharpening surface, such as an oil stone 1.3. In such aconstruction, when the roller carriage has been adjusted to support thecutting edge at the proper angle to the oil stone surface, the toolholding frame may be freely moved back and forth, thereby moving thecutting edge of the tool back and forth over the stone and at the properangle thereto; In Fig. 5 I have illustrated this same construction ofholder applied to a grindstone 14 of the circular revolving type, thethreaded standard 8 being adjusted to incline the cutting edge of achisel 15, for instance, carried by the holder, at the proper angle forsharpening. The roller 12, of

course, rests on the edge of the grindstone ,and 1s revolved as thestone revolves.

From the foregoing it will be evident that I have provided a tool holdercapable of a wide range of use in connection with various sizes ofcutting tools, and provided with adjustable supporting means affordingangular adjustment of the body and tool and affording a support for thetool holder ca pable of free rectilinearmotion to sharpen the same on aplane surface, and also adapted to properly osition and support the toolupon a curved rotating surface as well as adapted for use under variousother conditions of'work.

I have described and illustrated a preferable embodiment of theinvention, but desire it understood that the structure thereof issusceptible of modification withinthe spirit of the invention and thescope of the appended claims.

What I claim, therefore, and desire to secure by Letters Patent is:

1. In a device of the character described, in combination, an integralbody having a tool seat thereon and provided with ,tool clamping meansadjacent thereto, a support, for said body portion adjustable relativethereto, and meansfor locking said support in adjusted position. 7

2. In a device of the character described, in combination, an integralbody having an inclined portion forming a tool seat and provided withtool clamping means adjacent thereto, and a support for said bodyportion adjustable relative th'ereto whereby the angle of inclination ofa tool edge rela tive to a sharpening surface may bevaried.

3. In a device of the character described, in combination, an integralbod portion provided with a downwardly incllning tool seat at one endthereof, tool clamping means adjacent said seat, and a supportingcarriage for said body portion 'connected thereto adjacent its oppositeend.

4. In a device of thecharacter-described, in combination, an integralbody provided with a downwardly extending tool seat at one end thereofand having a threaded bore formed therein adjacent its opposite end,tool clamping means adjacent said seat, and a supporting carriagehavinga standard in adjustable threaded engagement with said bore andhaving an anti-friction supporting bearing at its base.

5. In a device of the character described, in combination, amain bodyportion having a downwardly inclining portion at its for ward endforming a tool seat provided with carriage provided with a supportingro1er at its lower end and havlng an upwardly extending standardthreaded to adjustably engage the threaded bore of said body portion,and means carried b said body portion for locking said standar inadjusted position.

6. In a device of the character described,

in combination, an integral body portion comprising an arm and adownwardly inclining portion extending therefrom to form a tool seat,and an independent support adjustably connected to said arm.

7. In a device of the character described, in combination, an integralbody portion comprising an arm, a downwardly inclining portion endingtherefrom and provided with a tool seat thereon and with a bracketoverstanding and-spanning said tool seat, clamping means mounted in saidbracket and adapted tobe adjusted to engage and clamp a cutting tool onsaid seat, a supporting carriage in adjust-able engagement with said armand means for locking said carriage in adjusted position relativethereto.

8. In a device of the characterdescribed, in combination, a main bodyhaying a downwardly inclining portion at its forward end forming a toolseat and provided with a bracket extending transversely of andoverstanding said seat, a tool clamping member carried by said bracketand adapted to engage and clamp a tool on said seat, said body having athreaded bore formed therein adjacent its rear end, and a supportingcarriage provided with a roller at its lower end and having an upwardlard threaded to engage t e threaded bore of said body portion.
